bios
Enables the basic input/output system (BIOS) in preparation for Boot Over SAN. The BIOS is the 
firmware code that, when first powered on, is a type of boot loader.
NOTE
Refer to the Brocade Adapters Installation and Reference Manual for more information about 
configuring BIOS.
Synopsis
bcu bios --query <port_id
bcu bios --enable <port_id> [-s speed] [-o auto|flash|firstlun] [-p pos] {-b pwwn,lun}*
bcu bios --disable <port_id
Description
You must enable BIOS to support boot over SAN for a port. If disabled, the host system cannot boot 
from Fibre Channel disk drives. BIOS must be enabled on only one adapter port per host in order to 
boot from SAN. The default setting for the boot BIOS is enabled. 
The port ID can be any of the following:
Adapter ID
Port ID
Port WWN
Port name
Port hardware path
Operands
--query
Queries the boot-over-SAN configuration.
port_id
Specifies the ID of the port for which you want to display information.
--enable
Enables the boot over SAN configuration.
port_id
Specifies the ID of the port for which you want to set the port’s boot from SAN 
attributes.
speed
Specifies the port speed as auto-negotiate.
auto|flash|firstlun
Specifies the following options for obtaining boot LUN information:
auto - Enables auto-discovery. When enabled, the boot LUN identification 
is provided by the fabric.
flash - The adapter obtains the boot LUN information from flash memory. 
Values are saved to flash when you configure them and save them 
through the BIOS Configuration Utility, HCM, and BCU.
firstlun - The host boots from the first LUN visible to the adapter that is 
discovered in the fabric.
pos
Specifies the position for storing the boot LUN information in the -b pwwn, lun 
operand. The range is 0-3. The LUN information specified in position 0 is used 
first to boot from SAN, then information specified for positions 1, 2, and 3.
